Antique Rim Lock

Brass plaque - 'IMPROVED STEEL CASE'

Warded
c/w Key

Approximate measurements:-
Width - 5 7/8" (148mm)
Height (max) - 3 3/4" (94mm)
Keyhole backset - 1 3/4" (45mm)
Follower (knob) backset - 4 1/4" (107mm)
Follower opening size - 5/16" (7.5mm)

Lock is in very good working order. Most of the original black paint finish has worn away (blacking paste has been applied to the case). Brass plaque has an area of slight damage along the outer edge alongside the follower. Note, keep missing (excellent cast replacements are widely available).
